The tubes-19' are providdgeaeh, with a cleatl 23 arranged to face awafrom 'thje 'p'os'ts l2 and tubes 15', and in 'oi de j-to maintain thisof the apparatus, andf-pa ssafrbd 25 longi tudlnally 'throiighthe block21 and through the slots 2410f saidtubes 19.-

to the 'level of thecleats 23. The 'legis" then supported by two or moreslings from bar 18 to hold the injured leg. After this is accomplishedthe fracture is set as follows: The adhesive straps fastened just belowthe knee joint are also fastened on both sides to the cleats 23 on posts19, this holding the leg in one direction. The adhesive straps fastenedto the foot are also fastened to the part 80, the swivel head of theextension screw 28. By rotating the screw 28, the part does not movewith the screw and therefore does not hurt or twistthe leg. The pullproduced by rotation of screw 28 is gradual and therefore the extensionproduced this way to set the fracture gives only The foot is also heldin proper anatomical line by a sling support to bar 18. Having set thefracture this way, the leg is held in place certain and tied, as if itwas held in a vise. Now a final examination is made if everythingis inthe proper anatomical line and then the plaster. cast or any otherpermanent dressing is put on. v If the plaster cast fits well, it isnotnecessary to put a weight on the foot to keep upextension. The legcan remain in the apparatus or may be removed and placed on a pillow. Aspain to the'patient is hereby so much reduced. most fractures can be setwithout chloroform. Further there is plenty of room around the .legfordressing, so that it is practically as easyto treat a compoundfracture as a sunple fracture with the aid of this apparatus. Theapparatus is extended on the foot end, so that the healthy leg cannotreach the cross bar 9. This cross bar 9 prevents tipping of theapparatus.

My apparatus is adapted for either leg and may be set up or knocked downin a few minutes and can be packed in a small parcel for transportation.

'While the cleats and anti-rotation means of tubes 19 are not shown inthe application filled herewith. nor the means for vertical adjustmentof the tubes, as shown herein, it will be obvious that I may employ themtherein.

In practice, the injured leg is placed between the tubes 19, along theboard 6, the tubes 19 being preferably out of operative position whilethe patient is being placed in position although not necessarily. A

bandage isnow placed about the ankle of the injured leg and attached tothe head 30, the screw 28 then being rotated to apply the desiredtensicnto the leg, one or the other of the'posts 13 bearing against the trunkof the patient at the crotch between his legs to prevent movement towardthe adjusting screw 28 while tension is being applied to the injuredleg. One or more slings may now be suspended from the bar 18,to holdtheinjured leg in convenient and comforting screw is overcome.

postsl3 against the patient. .As the adjust-- ing screw is rotated,itwill be observed that the head 30 does not rotate and the bandage orstrap connected therewith'is -not, therefore, twisted and the torsion ofthe injured-8o leg because of the adjustment of the tension- Myapparatus is adapted for either leg, and may be set up or knocked downin a. few minutes and, as stated, llwill make the posts and tubesapplicable toeither this apparatus or to the one shown inthe applicationfor Letters Patent filed herewith,=thus minimizing the number thereof,their weight, and the space occupied thereby when packed fortransportation. .1

While the cleats and anti-rotation means of the tubes 19 are notshown inthe appli cation filed herewith, nor the means for ver tical adjustment.of the tubes, asshown; herein, it will beobvious that I may employ themtherein, or I may employ the specific forms shown therein in this formof apparatus, this being within my intent and with in thespirit-of myinvention. 1

Having fully described myinvention, whatl claim as new and desire tosecure by Letters Patent is :Q .1 I
